HM62W8511HI Series
4M High Speed SRAM (512-kword × 8-bit)
ADE-203-1036A(Z)
Rev. 1.0
Apr. 15, 1999
Description
The HM62W8511HI is a 4-Mbit high speed static RAM organized 512-kword × 8-bit. It has realized high
speed access time by employing CMOS process (4-transistor + 2-poly resistor memory cell) and high speed
circuit designing technology. It is most appropriate for the application which requires high speed, high
density memory and wide bit width configuration, such as cache and buffer memory in system. It is packaged
in 400-mil 36-pin SOJ.
Features
• Single supply : 3.3 V ± 0.3 V
• Access time 15 ns (max)
• Completely static memory
No clock or timing strobe required
• Equal access and cycle times
• Directly TTL compatible
All inputs and outputs
• Operating current : 130 mA (max)
• TTL standby current : 50 mA (max)
• CMOS standby current : 5 mA (max)
• Center VCC and VSS type pinout
• Temperature range: –40 to 85°C
